During a short viait, in January, 1888, to the northern part of the peninsula of Baja or Lower California, a small collection was made of the rocks occurring near Ensenada de Todos Santos, and along the section from there to the Colorado Desert. A description of the general geology along this route has been published in the Proceedings of the Academy.^ The rocks collected have recently been subjected to a more careful investigation, the results of which are contained in these notes. A few facts regarding the geological structure of the region are here necessarily repeated, while for detailed accounts, maps, profiles, etc., the reader is referred to the paper just mentioned. The rocks described may be grouped in five divisions : I. Granite and diorite. II. Paleovolcanic effusive rocks (quartz- porphyrites). III. Neovolcanic effusive rocks (basalt). IV. The slate series. V. Diabases. *Proc. Cal. Acad. Sci., 2ud Ser., Vol. I. Part 2, 188S. 2d Ser., Vol. n. Issued June iH, 1889. 2 CALIFORNIA ACADEMY OF SCIENCES. I. — Granite and Diorite. It has been shown in the paper referred to that the struc- ture of the peninsula at the latitude of Ensenada is that of a monoclinal mountain range with a gentle slope towards the Pacific and an abrupt faultscarp, facing the Colorado Des- ert. Furthermore, that the range is chittiy made up of a coarse-granular granitic rock, in which are intercalated several smaller areas of more or less altered slates, dipping towards the east at a high angle. Volcanic flows of differ- ent age are spread over the long western slope, and are especially accumulated in heavy masses near the Pacific. Again, at the foot of the faultscarp, near the western limit of the Colorado Desert, eflusive rocks occur, the age of which probably is pliocene, or recent. In the paper quoted, the granitic rock has several times been described as a hornblende granitite (Rosenbusch), being a coarse granular mixture of biotite, hornblende, feld- spar and quartz. From the examination in the field and the great resemblance to the granitic masses of Southern and Central California, there seemed to be but little doubt that this would be the correct classification. The detailed petrographical examination of specimens from very different localities along the section has shown, however, that the predominent feldspar usually is a plagio- clase, and that the orthoclase only occurs in comparatively small quantities, or may even be entirely absent. While the quantity of hornblende and biotite maj vary within certain limits, the general habit and appearance of the granitic rock is remarkably constant from Ensenada to the desert. It is rather coarse-grained and easily disinte- grating, giving to the bluffs the well known ' ' woolsack- structure." When decomposing, it often assumes a yellow- ish color, due no doubt to the large proportion of ferromag- nesian silicates which it contains. PETROGRAPIIICAL NOTES. 3 Detailed Description. 1. A specimen from Ensenada, corner of Galvez and Tenth street, is macroscopically a coarse-grained rock with fresh feldspar and quartz. Hornblende is present in much larger quantity than biotite, and on the whole there are more ferromagnesian silicates than usually. Under the microscope it is seen to consist of a hyphidio- morphic granular mixture of quartz, plagioclase, hornblende, moDoclinic and rhombic pyroxene and biotite. The mono- clinic pyroxene ftrms ill-defined, short and colorless prisms, considerably decomposed and obscured by chloritic and uralitic aggregates. More frequent than the monoclinic pyroxene, is a rhombic form of the same mineral, probably hypersthene, occurring in irregular grains or short prisms; the pleochroismus is distinct ranging from reddish to light green; it is frequently decomposed in the same way as the monoclinic pyroxene. The primary hornblende is of a brownish green color, has the usual absorption and pleo- chroismus, and is often intimately connected with the pyroxene, being grown together with it or even surround- ing it. Besides this normal hornblende, there is some uralite formed from the pyroxene and distinguished from the first mentioned mineral by its bluish green color. A yellowish brown biotite in foils, which show no bending or compres- sion, is also an imj^ortant constituent of the rock. Magne- tite, much apatite and zircone occur. Among the feldsjDars the plagioclase certainly predominates. There is probably some orthoclase, although this cannot be definitely stated. The plagioclase is more or less idiomorphic,with generally short lathlike or square forms. Often twinned accord- ing to both the albite and the pericline law; zonar structure wath correspondingly differing extinction is not unfrequent. This plagioclase is probably an andesine or an oligoclase. 4 CALIFORNIA ACADEMY OF SCIENCES. Between the plagioclase crystals, and closely following their outlines, lie numerous grains of clear quartz with com- paratively few fluid inclusions. The rock, according to this description, should be classi- fied as a pyroxenic facies of quartz-mica diorite. 2. Another specimen, also from Ensenada (corner Galvez and Fourteenth streets), is macroscopically a fresh, not very coarse grained mixture of hornblende, biotite, feldspar and quaitz. Under the microscope foils of brown mica and irregular grains of a dark green hornblende form the prin- cipal part of the ferromagnesian silicates; there are also, however, a few prismatic grains of a colorless augite (m.i- lacolite). Plagioclase is present in large quantities with the usual, partly idiomorphic prismatic forms, and between them lie numerous quartz grains with fluid inclusions. The rock should, hence, be characterized as a quartz-mica diorite. 3. A specimen of beautiful and fresh granitic rock was collected near the middle line of the peninsular range, at the east side of San Rafael Yalley, on the road from Real to Campo Nacional, near mouth of Canada del Sur. Very fresh, coarse granular rock with hornblende crystals up to 10 mm. long, biotite foils, white, often striated crys- tals of plagioclase up to 8 mm. long and much quartz. Under the microscope, zircone and apatite, in small quan- tities, a little magnetite mostly associated with hornblende. Biotite in straight, fresh foils, yellowish-brown, and with very strong absorption, forms inclusions in feldspar and hornblende. Dark green hornblende also with very strong- absorption: a, olive green; b and c, dark green; absorption of b nearly equal to that of c; one or two large, approxi- mately square grains of uralitized pyroxene, probably dial- lage or augite. The plagioclase of which a large quantity is present is as usual partly idiomorphic, and in all respects PETROGRAPHICAL NOTES. 0 agrees with that in the specimens already described. It contains many small biotite needles. Orthoclase is perhaps present in very small quantity. Quartz is abundant, filling the interstices between the feldspar grains, and containing very numerous fluid inclusions, with moving bubbles. There are no signs of mechanical deformation among the constituents. Hardly any of the quartz grain show undu- lous extinction. In order to determine more accurately the character of the feldspars, a separation by specific gravity was made by means of the Thoulet solution. A quantity of 4 grms. was used, and reduced to 0.4 mm. grain. The result was as follows: Beginning with the solution at the specific gravity of 2.75 hornblende and biotite fell ; between 2.75 and 2.66 no appreciable amount was precipitated, while at about 2.655 a large quantity of feldspar, mixed with a little quartz fell. The largest proportion of quartz fell somewhat below this specific gravity. Only a few grains remained swimming with the solution at 2.60-2.59. The complete separation of feldspar and quartz was found to be somewhat difficult, their specific gravities being so nearly equal. The percentage of the different constituents would approximately be as follows: 25 % hornblende and biotite. 40 ^f' plagioclase. 35 /r quartz. The feldspar being so thoroughly fresh, it is safe to con- clude from the specific gravity that it is an oligoclase, per- haps somewhat approaching the andesine. The rock is thus characterized as a quartz-mica diorite. 4. A fourth typical specimen, collected near the summit of the main range at Hansen's Ranch is a coarse granitic 6 CALIFORNIA ACADEMY OF SCIENCES. rock with more biotite and less hornblende than the pre- ceding. Fairly but not quite fresh. A separation of this rock by Thoulet's solution gave the following result, size of grain and quantity being the same as before : 18%' biotite and hornblende; 66% fell at 2.64-66, con- sisting of quartz and plagioclase, sp. gr. of the latter being nearly equal that of quartz. This portion was not further separated. 16% fell at 2.55-57, consisting of orthoclase. This portion was tested with silico-hydrofluoric acid and gave abundant Ka, no Na reaction. The numbers of per- centage are of course only approximate. Here, then, ortho- clase is present, but not in very large quantity; there is certainly a very large excess of plagioclase, and this rock should also be classified as a quartz-mica diorite. 5. A specimen, taken from the foot of the supposed fault- scarp, about one-third mile west of Real del Castillo (San Rafael Valley) and near a slate contact, differs considerably from those already described. It is a rather fine-grained, granitic rock of whitish color and containing a few biotite foils. Under the microscope it is seen to consist of some partly idiomorphic plagioclase crystals, a few greenish- brown biotite foils, very little muscovite and a predomina- ting allotriomorphic mass of orthoclase and quartz, oftener showing a tendency to granophyric structure. The feld- spars contain, in consequence of an incipient decomposi- tion, a considerable amount of muscovite. The specimen may be characterized as a granitite. The chief interest, however, centers in the marked me- chanical effects of pressure which this section shows. Among the quartz grains undulous extinction is quite com- mon, and many of them are even broken and shattered. The feldspar grains show still more markedly undulous and ir- regular extinction and also frequently peripheric crushing (Randliche Kataklase). Thus, the internal structure of the petro(;raphical notes. 7 rock indicates that it at one time has been subjected to in- tense pressure; a conclusion interesting in view of the occur- rence of the specimen at the foot of the supposed faultscarp and in close vicinity to the slate contact. The detailed description of the rocks from various locali- ties in the granitic range, seems to indicate that the largest part of it is composed of a quartz-mica diorite, containing a varying but small percentage of orthoclase. Nos. 1 and 5 both differ from the normal type, the former being more basic, approaching the augite diorites, or even the norites by its percentage of monoclinic and rhombic pyroxene, the latter more acid and a nearly normal granitite. It is well known that large masses of coarse granu- lar rock, though they, geologically, may be a unit, do not always remain constant in structure and mineralogi- cal composition. Irregular and ill-defined areas of more or less basic character are often included in the predominant rock, and frequently connected with it by means of transi- tions. Thus, although the main mass of the Peninsular Sierra along this section may be, and probably is, made up of quartz-mica diorite, still it does not necessarily follow that this character should be retained beyond this line. Southward the great massive continues down the penin- sula for at least two hundred or three hundred miles, where at last it disappears under the mesa sandstones. Northward it continues through San Diego and Los An- geles counties, and forms the larger part of the Sierra Nevada until, in thcmclus subgen. nov. Adipose fin present. 44.

BELDING. There has been much confusion concerning the small thrushes that occur in California, arising mainly, I be- lieve, from the neglect of observers to verify their observa- tions by securing specimens. Hoping to induce the orni- thologists of California to give much closer attention to the four or more small thrushes that are found here, I have taken the libertj^ to present herein a portion of the data which came into my possession while superintending the collection of information concerning the migration aod distribution of birds in the "Pacific District,"' and have quoted, sparingly, from several authors, such matter as I thought appropriate. I, am indebted to my young friend, Walter E. Bryant, for overseeing the publication of this paper. All measure- ments are in inches or parts thereof, and the nomenclature of the American Ornitholgists' Union has been followed. 1. Turdus ustulatus (Nutt.) Russet-backed Thrush. — This is the one best known by our collectors, as it is less shy, and is perhaps the only one of these thrushes that breeds in the cultivated parts of the State, to which it appears to be mostly restricted. My observations at San Diego incline me to believe that it does not arrive in California from the south much before the first of May, although it is at least iDOssible that individuals may arrive in the interior of the State from the Colorado and Mojave Deserts by way of i;he Tehachapi Pass and other interior routes much sooner than along the cool sea coast, as is undoubtedly the case with other species. It leaves central California about the first of September. Dr. Cooper (Proc. Nat. Mus. , 1879, p. 249) says: ''It left Haywards September 20, 1875." It has been collected as far south as 2d Ser.. Vol. 11. [ o ] October 1, 1889. ' 58 CALIFORNIA ACADEMY OF SCIENCES. Central America in winter, as far north as Alaska in sum- mer. It appears to be very rare east of the Sierra Nevada Mountains. It winters entirely south of California, al- though niather Xantus nor myself found it in the Cape St. Lucas region. Colonel Grayson found it abundant on Tres Marias Islands, in January. Mr. E. W. Nelson (Keport upon the Natural History Collections made in Alaska, 1877- 1881, p. 217) says: " At present it is known only from the soutiieastern coast x3ortion of Alaska." Mr. John Fannin, of Burrard's Inlet, British Columbia, says: " It is an abun- dant summer resident." Dr. J. G. Cooper (Nat. Hist. Wash. Ter., 1860, p. 256) says: " This is one of the most common summer residents in the wooded parts of the Territory, ar- riving in May, and remaining until the beginning of Septem- ber." Dr. Suckley, in the same volume, says it was "Quite abundant west of the Cascade Mountains." Prof. O. B. Johnson (Am. Nat., July, 1880, p. 486) says it is " Very common during the breeding season" in the Willamette Valley, Oregon. The only record of its occurrence east of the Sierra Nevada Mountains, as far as I can learn, is Mr. Ridg way's record in his report on the Ornithology of the Fortieth Parallel, p. 396, he having collected a specimen in the Trnckee Meadows near the eastern base of the Sierra Nevada. Probably few breed as far south as northern Lower California, although the species was very common between Campo and San Diego, May 16, 1884, and quite as common south of Campo, in the mountains, to near Han- sen's, as late as May 14 of the same year. I saw but few between San Diego and San Pedro Mountain, near the Gulf of California, in May, 1885. I first saw the species at San Diego in the spring of 1885, on May 3, when I shot both sexes in pepper trees, Schinus Molle, in the streets. The following are mostly from migration notes of 1884 and 1885: San Diego. April 25, 1862, April 20, 1875, arrived. Dr. J. G. Cooper, Proc. Nat. Mus., 1879, p. 245.

Merrill, Auk, October, 1888, p. 365, says: "It arrived at Fort Klamath, Oregon, about May 20, a few nesting about the Fort and in suitable situations in the mountains near the Fort." Fort Walla Walla, W. T. May 20, 1885, first seen, four birds; next seen June 2; by -June 10 it was common. It is somewhat common here in breeding time. Dr. J. W. Wil- liams, U. S. A. Mr. Nelson, in Proc. Boston Soc. of Nat. Hist., Vol. XVII, p. 355, mentions having seen it at or near Nevada City, Cal., as late as November — an error, I am sure, the November birds having been probably the dwarf thrush, which I think 60 CALIFORNIA ACADEMY OF SCIENCES. is the only form of the small thrushes that is found in cen- tral California as late as November. The eggs of T. ustidattis are pale bluish-green, and always spotted, I believe, in this latter feature differing from the ej^jgs of T. aonalasclikcv and T. a. aiidtihoid. The song of T. nstalatus was well described by Nuttall as resembling "irdt-2vif, f villia-f villia'\ Prof. O. B. Johnson, in "Birds of the AVillamette Valley," published in the American Nat- uralist, July, 1880, p. 486, says: "The alarm note is a short whistle ' whoet,' identical with that of a person attract- ing the attention of a dog; the call-note is a tremulous ' lohaat-r-r-r ' in the same key as the alarm note, only ending in a trill." He describes the song as "A peculiar whistle, ascending a scale of four notes, and sounds like holsey — govendy — govindy — goveendy.'' Dr. Suckley says : "Its voice is a low, soft, sad, lonely whistle, generally confined to one note about three seconds in length," from which I infer that he did not hear the full song of T. tistidatus. Most authors describe its notes in such general, indefinite terms as to be useless for purposes of identification. The notes on this species, T. stvainsonii and T. '' nanus ^' in Ornithology of California are very misleading. (See Dr. Cooper's correct- ions in these Proceedings, Vol. 6, 1875, pp. 190-192.) 2. Turdus ustulatus swainsonii (Cab.) Olive-backed Thrush. — Habitat, Eastern North America and westward to the Upper Columbia Biver and East Hum- boldt Mountains, straggling to the Pacific Coast. Breeds mostly north of the United States. (Check List of the American Ornithologists' Union.) In 1885 or 1886 I enquired of Prof. Ridgway if he knew that this thrush had been collected in California, to which he replied — "We have in the Smithsonian Collection but one specimen so labelled, and this I find, after a careful ex- amination, is T. tistidatus in somewhat Avorn and faded plumage." In the summer of 1888 I collected three speci- SMALL TITRUSIIES OF CALIFORNIA. 61 mens in the mountains of Calaveras County, and these were compared witli skins of T. n. swai)isonii in the Smithsonian, and identified as typical T. v. sfrai}iso)}ii by Dr. A. K. Fisher. Prof. Ridgway also thinks them T. u. sioainsomi , and my specimens collected in Calaveras and Tuolumne Counties in May and June, 1889, fully confirm the opinions of these gentlemen, as I find no difference between them and types of T. ti. sunnvsonii from the Atlantic Coast, which were kindl}^ selected and sent me by Prof. Eidgway and Mr. Brewster. I have a specimen I shot in Sierra Valley, Cali- fornia, on the east slope of the Sierra, June 20, 1885, which I think belongs liere. I think this form is common in the Sierra Nevada mountains of California in summer, as I have heard its song in Tuolumne, Calaveras, Placer, Butte and Sierra Counties — a song which resembles the song of T. vsfulatiis, but lacks its power, sweetness, and ringing- tones. The call and alarm notes of both forms are, how- ever, almost identical. The note of alarm of tlie California T. ?/. sivainsonii is a short, soft, musical whistle, wliich may be .represeuted by the word " ichoety The call is also a whistling note, higher than the note of alarm, lasts two or three seconds and is suggestive of the peep of our small hog Hyla regiUa . It has an enquiring expression. I think it louder than the call of T. itstidatus. Examples of songs of Swainson's Thrash, which I copied as uttered in Calaveras County, California: All of the notes excepting the one or two introductory ones of the soncs are confluent or slurred. 62 CALIFORNIA ACADEMY OF SCIENCES. Those 1 collected in Calaveras County, at altitudes varying from four tlioasand to five tliousaiid feet, were in dense, damp forests, but I have also found colonies ill willow thickets in grassy mountain meadows as at Bear Valley near Emigrant Gap and Siena Valley, at both of which places I got poor specinjens. According to Mr John Fannin, of Burrard's Inlet, B. C, it is jin abundant summer resident of that region, arriving May 1, 1884, and May 12, 1885, but was not common in the latter A ear until May 27. Mr. Nelson (Eeport upon the Natural History Collections made in Alaska, p. 218,) says: "It breeds on the Upper Yukon Biver." Prof. Bidgway says, in his report on the Ornithology of the Fortieth Parallel, ]). 397, that not a single individual of the smaller thrushes was met with after leaving the Sierra Nevada until arriving at the East Humboldt Mountains, where the olive-backed thrush was encountered in considerable numbers during the season of their southward migration. According to Baird, Brewer and Bidgway, the eggs ex- hibit noticeable variations in size, shape, and shades of coloring, bearing some resemblance to those of T. usfalatus. Mr. Nelson says the eggs of T. n. swcdnsonii and T. alicice are absolutely indistinguishable, both in shape and size, as also are the nests, according to his observations — and that both breed together on the Yukon Biver in Alaska, T. (dicice being the more numerous on the Lower Yukon. As the moutli of the Yukon Biver is nearly as far west of San Fran- cisco as San Francisco is west of New York, it seems strange that the individuals of T. alicice which spend the summer in Alaska do not follow the Pacific Coast in their southern migrations and pass through California. This remark will apply to other land birds which spend the summer in Alaska and other parts of the northwest coast and winter entirely in the Tropics. The physical features of the coast probably determine the line of flight. SMALL THRUSHES OF CALIFORNIA. 63 3. Tardus aonalaschkse Cimel. DwAiiF Hermit Thursh. — Habitat, Pacific coast region, from Alaska to Lower California, e;ist, during migrations, to Nevada and Arizona. Breeds from California north- ward. (A. O. U.) It is common in winter in this State below the snow belt and I have seen it as high as Big Trees in January, nearly five thousand feet above sea level. It is common in the mountains of southern Lower California in winter. Accord- ing to Mr. Nelson (Report upon the Natural Flistory Col- lections made in Alaska, 1887,) there are no records of its occurrence in Alaska much north of Sitka, where it appears to be confined to the mild climate of the timbered coast. Mr. Fannin, of Burrard's Inlet, says: '* It is a rare summer resident." It may breed in California, but I doubt if there is any proof that it does so, although I thought differently until recently. I supposed I had found it breeding in Cala- veras County, but a careful examination of several skins I collected there in summer, satisfies me that they are the Big Tree thrush, as explained elsewhere in this paper. Cap- tain Bendire found a nest at Camp Harney, Southeastern Oregon, June '28. It was on the ground and contained three young and an addled egg, the latter pale green in color, probably paler than usual. Unfertile eggs are often paler and smaller than the average. Dr. Heermann, in Pacific Kailroad Eeports, Yol. X, refers to the breeding of this species in the sandhills about San Francisco, but does not mention T. iistidaius, although he collected about three years in this State. The species I saw at Stockton, June 8 (Proceedings National Museum, 1879), was, like Dr. Heer- man's, probably T. ustulatus. On that day I found a colony of small thrushes in a large willow thicket along the Cala- veras River, but could not get a specimen. I saw them in the middle of the day when they were not singing. AVithout specimens, observations on the small thrushes have but little or no value. Dr. J. G. Cooper (Proc. Cal. Acad. Sci., 1875, 64 CALIFORNIA ACADEMY OF SCIENCES. p. 190) says: " The notes given by me in ttie lower five lines of this page (Ornith. Cal., p. 4) belong properly to the next species [T. ustulatas], as it is scarcely probable that any of this [species] remain ia the lower country of California, or even in the mountains in summer, unless above an elevation of 8,000 feet, as does its Rocky Mountain representative, var. auduhoni (Baird). The song of that, and of the east- ern race, var. pallasii Cab., being described as resembling that of the wood thrush (T. musteUnns), with which I am familiar. I am sure that I never heard it in the Sierra Ne- vada up to 8,000 feet altitude, nor in the forests of Wash- ington Territory, and that of var. nanus cannot be very dif- ferent. It is the winter thrush of California, common from September to May." ''I was misled in giving T. nanus as the common summer thrush of California, both by its having been given by all previous authors as the only small brown thrush found in the State (ustulatus being limited to the north)," etc. I have not seen the species at nor south of San Diego later than April 8; this was at San Diego in the very wet, backward spring of 1884. Mr. Blaisdell saw it at Poway as late as April 12, 1885. My latest Stockton record is April 25, 1879, when snow was low down in the mountains. Mr. Proud last saw it at Chico April 28, 1884. Dr. J. C. Merrill (Auk, Oct., 1888, p. 365), took a female at Fort Klamath April 29, but did not again see the species until May 11, when after a few days of cold weather it' was abundant. Mr. A. W. Anthony first saw it in the spring of 1885, at Beaverton, Oregon, on April 18. Dr. Williams noted its arrival at Fort Walla Walla April 27, 1885, and that it was common by May 15. Young were seen June 30. Observations bearing on its southward migration are the following: Mr. Henshaw (Report Wheeler's Survey, 1879), says: "By the last of August it was found numerous along the foothills of the Cascade Range of Oregon " (east slope). I have noticed its arrival at the summit of the Sierra Nevada, lat. 39° 20' N., September 22, in 1878, September 25, 1885, and have seen a few in the Sacra- SMALL THRUSHES OF CALIFORNIA. 65 mento Valley, in about the same latitude, by October first, but the species is not usually numerous in the valley until about a month later. Mr. Henshaw (Report AVheeler's Survey, 1876), says none were seen on Mount Whitney until the last of September. The migration was at its height from the fifth to the fifteenth of October. Mr. Blaisdell first noticed this species at Poway on Oc- tober 25, 1885. Dr. Cooper (Proc. Nat. Mus., 1879, p. 245) first saw it on Santa Catalina Island, October 30, 1861. Perhaps I should give full credence to Mr. C. II. Town- send's Mt. Shasta record (Proc. Nat. Mus., 1887, p. 231), although he did not get the individual seen July 25, 1883. Mr. Brewster (Auk, Oct., 1888, p. 365) says Dr. Merrill's Fort Klamath specimens were " Quite as gray as in average Colorado specimens of audahoni.'" The wing of the female measured 3.23; those of the three males 3.50, 3.55, 3.55, being much smaller than my Calaveras County specimens of T. seqiioiensis. I do not know that I have ever heard the song of the dwarf thrush. The name of the dwarf thrush, nanus, is very appropriate for this form. Mr. Nelson (Alaska Ke- port, 1877-1881, p. 218) says: "Since the Unalaska thrush was described, not a single specimen of any species of Hylociclila has been found on this island by the various naturalists who have visited its shores, a fact of itself cal- culated to raise suspicion as to the correctness of the iden- tification of Gmelin's name." Stability of ornithological nomenclature is very desirable, but if there is the least shadow of a doubt concerning the applicability of Gmelin's harsh aoonalascensis to this thrush, the bird, the reader and Avriter should have the benefit of the doubt, and nanus, guttatus, minor, or almost any name should be substituted for it. Dr. Cooper recently wrote me: ' ' I heard some years ago from Mr. W. A. Cooper that the dwarf thrush had been found breeding in the redwoods of Santa Cruz County. It may be your form or some other." Dr. Cooper thinks the Santa Cruz bird should be investigated, to which I cordially assent. 60 CALIFORNIA ACADEMY OF SCIENCES. 4. Tardus aonalaschkae auduboni (Bcaird). Audubon's Hermit Thrush. — According to Ridgway's Manual of North American Birds, its habitat is the "Eocky Mountains, from northern borders of United States south to highhmds of Mexico and Guatemala." Mr. Henshaw, in Report Wheeler's Survey, 1879, says: '"During the past sum- mer the important fact was ascertained that this form of the hermit thrush, instead of being strictly limited to the Rocky Mountains -^ -^ -- -^^ breeds along the eastern slope of the Sierras. During the summer of 1877, I lieard in several of the sub-alpine valleys of Northeastern California, what were without doubt Audubon's thrushes, but failed to secure specimens. Here they were evidently not very nu- merous; but in the mountains back of Camp Bid well the succeeding season, the same thrush w^as -^ -^ -^ ^ identified by shooting the bird. They were here very abundant, and at this date, July 19, the pine woods were filled by the sweet music of the males." In 1884, Mr. F. Stephens informed me that it had been found, breeding in the San Bernardino Mountains, but afterward said it might be the dwarf tlirush, as he failed to get the parent of the eggs he found there — he had w^ounded and could not find her. He further said: ''On look- ing over my skins, I find one w^hich is Audubon's, that I shot near Campo, San Diego County, and one which is vevf/ nearly intermediate between the dwarf thrush and Anduhon's thrush.'' Col. N. S.Goss reported, for the Notes on Migra- tion for the Pacific District, that he had found Audu- bon's thrush at Julian, San Diego County, altitude, 4,000 feet, on March 17, 1884. I made observations at Teha- chapi Pass and in the adjacent mountains from March 27, 1889, to April 12, but was not able to find a single small thrush, Avhicli was the chief object of my visit, though I ascertained that many species enter the San Joaquin Valley from the Mojave Desert by that route, at an early date, without much regard to the temperature in the Pass, appar- ently knowing that a milder climate would soon be reached SMALL THRL STIES OF CALIFORNIA. 67 5. Turdus sequoiensis Bei(Vn)<,'. Big Tree Thrush. — I should have added to the descrip- tion of this bird, published in these Proceedings, June 11, 1889, that its iris is bluish-browu, its mouth and most of the mandible are yellow, the tip of the latter brown. The male shot by me June 10, 1888, at close range, as it crossed a path when pursued by a small owl, was badly mutilated. Its wing was 3.80; tail, 3.25: tarsus, 1.16. The female shot June 25, 1883, is very pale and seems to be in faded nesting plumage. The two type specimens are, I think, in the best spring plumage, as tlie largest ovaries of the female were no larger than No. 1 shot. The small spots on the throat and breast appear to be a constant feature of this form, which I am confident is entitled to recognition, but it may prove to be a southern variety of T. aonalaschkce, just as T. a. aiKhihoni may be a southern variety of T. a. jycdlasii, though this is at variance with tlie almost unvarying rule, that the more northern variety of a species is the larger; or it may intergrade with T. a. cwdn- doni, which has been reported from the Sierra Nevada of California by three excellent observers, each of whom got, I believe, but a single specimen, and Mr. Henshaw's July specimen must have been too much faded for positive iden- tification ; and possibly all three were identical with the Big Tree thrush. The latter inhabits dense thickets in deep forests and is apt to be overlooked. Sometimes it wanders at a consid- erable height through the foliage of the firs and other coni- ferous trees, w^hen it is followed with much difficulty, even if its brilliant song is often heard. I shot the female type specimen while she was fluttering about seventy-five feet from the ground at the ends of fir twigs and catching in- sects in the manner of the warblers and tyrant flycatchers. I spent most of Jul}' 1, 1881, in trying to find, with the assistance of a young hunting dog, the nest of a pair of these birds, w hicli I had good reason to believe w^as in a certain hazel thicket. I failed to find the nest, probably 68 CALIFORNIA ACADEMY OF SCIENCES. because I sought for it on the ground instead of in tlie shrubbery. Later I found the same pair, as I supposed, with their young within a few yards of this hazel thicket, shot one of the juveniles in spotted plumage and sent it to the Smithsonian Institute (No. 85,623 of that collection). I saw both parents frequently during the month of July and observed that they were gray or pallid. I was often within a few yards of them, but heard no complaint or note of any kind from them, nor am I certain that I have heard this thrush utter a call note. On a solitary occasion a male that was within a few yards of me expressed its displeasure at my presence and gaze by giving several squalls which resembled the complaining cries of Pipilo cJilorurus, after which its two or more companions, that had been singing, w^ere silent. Its song was first heard in the spring of 1889, by J. Clar- ence Sperry, on May 12. The wonderful song of this bird I know to be much superior to the song of T. miistelinus, T. fnficescens, T. iistulatus and T, u. swainsonii. I never shot one of these sweet songsters without pangs of regret. While the songs of one individual may differ from those of another, the tone or voice of all is much alike and may be readily distinguished from those of T. iistulatus and T. u. swainsonii. The following examples, which I copied as they were ut- tered, will give some idea of its songs, though it is impossi- ble to represent them in all their wild beauty on paper. Some songs had irregular intervals and could not be cop- ied. No. 1. _^ fl^^^pg^i^g^j Slow. In the third group of notes, the third and fourth notes are in reality but one connected note, the latter portion of which is, in a measure, an echo of the third.

NOTES BY WALTER E. BRYANT. Mr. Belding has asked me to append any notes I may have or obtain bearing upon the species treated in this paper, with which object in view I have written to several correspondents for items and visited the dense wooded region south of Monterey, in search of small thrushes. The results are here given. 70 CALIFORNIA ACADEMY OF SCIENCES. Tardus ushdatus. — The records of arrival and time of nesting at Kaywards, furnished from the note book of Mr. Emerson, are as follows: Arrival. First set of eggs. Last set of eggs. April 27, 1882.

Tardus aonalaschkce. —The arrivals of this species at Ha}^- wards, as noted by Mr. Emerson, are: Dec. 18, 1880; none were seen in 1881; Nov. 28, 1882; Nov. 1, 1883; Dec. 25, 1884; Oct. 16, 1885; Dec. 20, 1886; Oct. 8, 1887. In 1885 they remained as late as March 28. I have seen them at Healdsburg, Oct. 5, 1888, and am quite positive that I heard their single plaintive note among madrone trees at Healdsburg, August 7, of this year. Dr. J. G. Cooper has written to me that in the "Addi- tions and Corrections to History of North American Birds" (Vol. Ill, p. 499), the statement that he had sent skins of T nanus {T. aonalaschkce) to the Smithsonian Institution is er- roneous; he says: "I sent the birds as ustulatus swainsonil, and they were from Saticoy, not Santa Cruz, wdience I sent nests and eggs as of T, nanus (Vol. III., p. 20). I further noted these points in Proc. Cal. Acad. Sci., Vol. VI, p. 190." Tardus sequoiensis. — I have compared five examples (four males) of the thrushes taken in Monterey County, July, 1889, with the types of Mr. Belding's new T sequoiensis, to which tlie}^ are probably referable, although not typical. They were collected in heavily wooded, deep caiions, and were found by quietly tracing the bird's song or by calling them with a screaking sound made with the lips. The notes of the Monterey County birds Avere simply lonely, plaintive SMALL TFIRLSIIES OF CALIFORXL\. 71 calls, and although iu the regi(3n for nearly a week I did not hear them actually sing. Tn the same locality I frequently heard the full song of T. ustuhdns. Near Canonville, Oregon, June 11, 1883, I shot a small thrush in worn plumage, which appears to be T. seqiioiensis (No. 1008, coll. of W. E. B.); the label is marked " nanmr in the handwriting of an Eastern authority, the skin being one of a small collection, which I carried East the following- year, and at that time such specimens were sap]:>osed to be faded examples of the dwarf hermit thrush. Mr. W. W. Price has recently taken two birds in the San Bernardino Mountains, which are by no means typical of T. seqiioiensis, and seem to be intermediate between T. seqiioiensis and T. aonalaschhe . In my opinion T. seqiioiensis will be found to merge into T. aonalaschJice when sufficient material is brought together, and consequently will stand as Turdns aoncdaschJae seqiioiensis (Belding). The Big Tree thrush appears to have no close relationship to T. a. audiiboni, further than being one of the rufous tailed group, to which belong T. aonalaschhe, T. aoualciscJikce aii- diihoni, T. aonalascJikre pallasii and T. cionalascJihe seqiioi- ensis. Mr. E. C. McGregor has searched in the Santa Cruz Mountains for T. a. seqiioiensis without success, but it un- doubtedly occurs there and is the same that I collected in Montery County and the one which Mr. W. A. Cooper re- ported as " Breeding in the redwoods of Santa Cruz County." Mr. William Proud, of Chico,lias looked for the Big Tree thrush near there, and in a letter to Mr. Belding writes: " I heard the song of a thrush decidedly ditferent from H. iistii- lataf' the song ' ' consisted of seven notes; the higher notes had a guttural sound, similar to some of those of H. ustidata.'' In a letter dated August 4, 1889, Mr. Belding writes that he has " found a few of the Big Tree thrushes at the Sum- 72 CALIFORNIA ACADEMY OF SCIENCES. mit [Placer County], and got a specimen July 22." The bird Avas a male, faded and worn; it measured, length, 7.40; extent, 12.10; wing, .3.80; tail, 3.10; tarsus, .15; bill from nostril, nearly .40. It was about fifty feet high in a leafless tree when shot. " This thrush," he further says, " is de- cidedly arboreal, quite as much as Townsend's Solitaire, and like it, goes from the ground well up into the large trees at a sharp angle." Mr. Belding has sent me three young birds of Tnrdiis aonalasclikce seguoiensis, which he collected August 12 and 27 this year at Lake Tahoe, Cal. They are about full grown, and quite as dark as adults of T. aonalasclikce. Dr. Cooper has hinted that T. a sequoiensis may be but the summer plumage of T. aonalaschkce, bleached out and otherwise changed in the dark but dry woods of the interior; but within a mile of the coast, in Monterey County, where dense fogs prevailed, I found this year birds that were un- like the winter j^lumage of T. aonalasclikce, and referable only to T. a. sequoiensis, although not as pronounced as the type specimens. Young. (No. 356, coll. of Cal. Acad. Sci., from Lake Tahoe, Cal., August 12, 1889. L. Belding).

About one hundred and fifty miles south of the United States boundary, and midway between the Pacific Ocean and Gulf of California, lies a high range of mountains, which is marked upon the later maps of the peninsula as ' ' San Pedro Martir." The region embraces a series of small ranges which rise from an elevated mesa, having a mean elevation of about 8,000 feet, and an extent of sixty by twenty miles. In these mountains are born the only streams that this part of the peninsula afi*ords, and an abundance of pine timber is found throughout the region. Many of the ranges on the eastern side of the San Pedro Martir rise to an elevation of 11,000 feet, or even, in one or two places, to 12,500 (?) feet. Arising as the region does from the dry, barren hills of the lower country to an elevation higher than any other on the peninsula or in Southern California, and presenting in its alpine vegetation and clear mountain streams features so different from the dry manzanita and sage-covered hills of the surrounding country, it is not unnatural to suppose that its animal life would be found to differ in some respects from that of the surrounding hills. It was not, however, until 1 had been in Lower California over two years that I was able to visit the locality and give it a little of the at- tention that it deserves. During the latter part of April and the first of May of the present year (1889) my friend, Mr. Charles H. Townsend, and myself spent two weeks in exploring the higher ranges of this region, and although tlie results of our trip are very flattering, we were by no means able to complete the work. About one hundred birds were taken, yielding the following- new forms, and others w^ill perhaps prove entitled to separa- tion wdien w^e have secured a larger series. 2d Ser., Vol. II.

Anthony from San Pedro Martir, Lower California, April 25, 1889, elevation, 8,500 feet.) Back, wings and tail, ashy brown with slight olive wash. Inner secondaries and tertiaries bordered with white, forming, when wings are closed, two parallel bars of white. Foreparts, above and below, slaty blue, slightly grayer above. Belly, rich chestnut, banded on the sides with bars of white and black. Flanks, rufous. Tibiae, ashy. Crissum, velvety black streaked with chest- nut. Throat, chestnut, bordered laterally with narrow black line, which in turn is bordered with white. A white mask surrounding the bill and changing to grayish on fore- head. Arrow plumes, black. Habitat. — Mountains of San Pedro range, Lower Califor- nia, reaching to valleys in winter. From an elevation of six thousand to ten thousand feet above the sea, in the San Pedro Mountains, I found this quail abundant, occurring wherever Avater and timber af- forded it drink and shelter, and only leaving the higher elevations when the frosts of winter make life in the lower valleys desirable, A few pairs bred about my camp atVal- ladores, six miles from the base of the range and 2,500 feet above the sea; but nearly all of the flocks that wintered along the creek at this point were gone in March, leaving onl}^ an occasional pair, which sought the shelter of the manzanitas high up on the hill-sides, from whence their clear, mellow notes were heard morning and evening, so suggestive of cool brooks and rustling pines, but so out of place in the hot, barren hills of that region.

I take great pleasure in iiamiug this excellent species for my friend, Mr. Chas. H. Townsend, of the U. S. S. Albatross, as a slight recognition of the much valuable work he has done for western ornithology. J. townsendi is probably the most abundant bird to be found in the timbered parts of the San Pedro Mountain, and is, I think, resident, as I have never, with a single ex- ception, taken the species at the base of the range. The characters described are remarkably constant. No. 2540, a fine adult male, sports the abnormal passerine number of thirteen rectrices, and has evidently lost a fourteenth. J. h. oregonus occurs along the base of the range in winter, but does not seem to join J. townsendi in nesting in the high altitudes. DIMENSIONS OF JUNCO TO WNSEXDI. Collection of A. W.

Habitat. — Mountains of Lower Calilornia, Mount Lassen, Cal., Puget Sound, Utah and Nevada. Named for my wdfe, Anabel Anthony. From the series of thirty adult birds before me I am able to find but three that can not be immediately referred to one race or the other; these are: No. 53319, coll. U. S. Nat. Museum, Carson City, Nevada; No. 82589, coll. Nat. Museum, Marin County, Cal.; and No. 821, coll. A. AV. Anthony, Washington County, Oregon. These are all male birds and midway between the two forms, having the bay of the breast scarcely divided by the blue, and but little rusty coloring on the scapulae. Three National Museum speci- 80 CALIFORNIA ACADEMY OF SCIENCES. mens which I have examined, from "Mount Lassen, Cal.," " Genoa, Utah," and " Paget Sound;" are undoubtedly re- ferable to S. m. anahelce. These, Mr. Eidgway writes me, are the only ones in the National Museum collection that match my specimens from Lower California. During our stay of two weeks on the San Pedro Mountain, both S. mexicana and S. m. aiiabelw were everywhere common; the latter, however, greatly outnumbering the specific form, and in a great measure flocking by itself. At a distance of one hundred yards it was quite easy to identify the two forms; and I do not think that either Mr. Townsend or myself were guilty of shooting a male bird the identity of which we were not sure of beforehand; the greater amount of blue in the plumage of the adult male giving it an appearance much darker than that presented by typical S. mexicana. Most of the S. m. anaheloe were paired and preparing to nest by May 1st; but I think S. mexicana were not yet nesting; they appeared to be birds that were still moving northward, and it is possible that later we would have found them all gone. It is my opinion that S. m. anahelce will prove to be a south- ern form of S. mexicana, wandering occasionally as far north as Puget Sound. A recent trip into the mountains of the eastern part of San Diego County, Cal., failed to bring to light any other than the typical form of S. mexicana. The following tables of measurements will show the rela- tive size of the two forms, and a slight though constant variation will be noticed in favor of the San Pedro birds, which are slightly larger than any S. mexicana which. I have examined : NEW BIRDS FROM LOWER CALIFORNIA. 81 DIMENSIONS OF SIALIA MEJTICANA ANABELJE. Sex :^ .-io^ H No. ! and 1 Age. Locality.

I. edited by walter e. bryant. Nesting Habits of the California Brown Pelican. (Pelecanus calif ornicus.) By a. W. AjsTHOny. It is my impression that no description has been given of the eggs of tliis species since its separation from the Atlan- tic form; at any rate, papers that treat npon the subject are not so common as to make another siiperfluons and a few notes upon the habits of the pelican devoid of interest. The largest colony that I have found thus far was discov- ered on San Martin Island April 12th, 1888. The island of San Martin lies about five miles off shore and nearly due west from San Quentin, Lower California, in about Lat. 30^ 33' N. With the exception of a few acres of sand on the east and northeastern sides, it is composed entirely of lava, which has escaped from an extinct volcano on the southern end of the island; the greatest elevation is found at this point, which is perhaps 450 feet above the sea. The entire island comprises about 1200 acres. Three days were spent here in investigating the bird life, most of which time was expended in making life a burden to a colony of about five hundred pelicans, which were found nesting on the north end of the island. The nests were located in groups of twenty or thirty about a quarter of a mile from the beach and about 250 feet above the^sea. They were largely com- posed of the accumulated filth of several generations of pelicans, and many of the older ones had obtained a height of three feet, evidently having been added to from year to year. Most of the nests were built on the tops of low bushes, but many were resting on the bare ground or placed 2d Ser. Vol. II. October 11, 1889. 84 CALIFORNIA ACADEMY OF SCIENCES. Upon blocks of lava. Sticks, twigs, kelp, sea grass, and in a few cases bones of defunct sea birds, were used as build- ing material, and a little sea grass spread over tlie top as a lining, no attempt being made to form anything more than a mere platform eighteen inches or two feet in diamater, and in nests of a single ^^ear's growth four or five inches in depth. At this date, April 12th, most of the nests con- tained young ranging from those just hatched to the full- fledged birds capable of flying. Many nests, however, contained eggs, and by careful selection about twenty sets were found that were fresh, or nearly so; others taken at random proved to be all more or less incubated. The usual set seems to be three; a few nests contained two and were probably not complete; while but one set of four was found. The fresh eggs were perfectly white, but as incubation began they became stained from the damp, decaying sfeaweed and kelp, which forms the liniag of the nest, and by the time they had been in the nest two weeks it was diflicult to tell what the original color had been. An oologist (?) whom I presented with a set of three stained eggs reported that he had cleaned them so thoroughly that they were much finer specimens than any of my fresh ones. When asked to describe the method used he informed me that he simply rubbed them wdth sandpaper until the shell was as thin as he considered safe. This method may be of value, but will hardly come into general use. A set taken at random from the collection of twenty- five, and which is perhaps a fair average as to size, measures in millimeters 83 x 48 ; 85 x 48 ; 72 x 50. The birds at this colony did not appear to be very wild, only flying up Avhen we had approached to within fifty or sixty yards and settling down again as soon as we had passed by. Flocks of from five or six to twenty were constantly ar- riving from far out at sea, flying in one long line, each fol- lowing directly in the track of the one next in front, and but just keeping above the water until within a few hundred GENERAL ORNITHOLOGICAL NOTES. 85 yards of the island, when they rose gradually to the eleva- tion of their nests. Towards night the flocks grew larger, as the birds that had been over to San Quentin Bay for the day's fishing began to arrive. These birds after fishing until sunset along the southern shore of the bay, gather in large flocks, and most of them fly directly up the bay, or almost at right angles with the course taken by those birds that fly directly towards the island. For some time I was at a loss to know where these flocks were going, as I knew that tliere was no resting place in that direction; but I found that after reaching the head of the bay, ten miles from the feed- ing grounds, they turned through a pass between the hills, and after flying five miles over land, reached the ocean at a point opposite the island, having flown eighteen or twenty miles to reach a point ten miles distant, rather than fly two miles over a range of hills one hundred feet high. Above ten per cent, of the birds, however, were wise enough to take the shorter route. Hundreds of pounds of small fish were scattered all about the colony, in little bunches or singly, having been disgorged entirely undigested. I could not see that the young were making any use of these provisions, nor did any of the birds of the island except the gulls. They were proba- bly designed, however, for the nearly fledged young that were still unable to fish for themselves. One apparently fat and healthy adult female, which I saw frequently during my stay at the island, had splintered the upper mandible so that it hung down upon her breast in two or three long strips, waving and flapping as she flew like pieces of shingle; she had probably struck a hidden rock in diving for fish. I did not find the pelican nesting on San Geronimo Island, fifty miles south of San Martin, but at Todos Santos Islands, opposite Ensenada, I am told that a few birds nest ever}' year. Mr. A. M. IngersoU informs me that about twcDty-five nests are to be found on one of the Coronados Islands. 86 CALIFORNIA ACADEMY OF SCIENCES, Occurrence of Phaethon cethereus and Capture of ^S'co^e- cophagus cavolinus in Lower California. By A. W. Anthony. Heretofore it has been considered rather unusual to en- counter the tropic bird north of Cape St. Lucas, although it has been regularly met Avith in that latitude. I think, how- ever, that it will be found to be ;> regular though perhaps a rare visitant to the entire Pacific coast of tlje Peninsula. In Jane, 1887, I saw tropic birds on two consecutive days at a point about fifty miles north of Cerros Island (Lat. 29° N.) I next observed them in September, 1888, wdiile on my way from Ensenada to San Quentin. As we v.-ere passing Cape Colnett, somewhere in the Lat. of 31° 15' N., a pair of tropic birds joined the ship and flew about with the gulls for some time; later in the same day a single bird was seen about twenty-five miles farther south. I am reasonably sure that I have seen one or two birds about the Todos Santos Islands, sixty miles south of San Diego. ^ As no Pacific Coast record has been given of the appear- ance of the rusty blackbird south of Alaska, I was not a little surprised when I encountered the species at my camp at the foot of the San Pedro Martir range in Low^er Cali- fornia, where a single male bird was taken December 12, 1888. No others were seen, nor w^as S. cyanocephalus found until some weeks later. Comparison of my specimen with Avinter birds from the Eastern States proves it to be typical S. carolinus. Nelson in his " Eeport upon the Natural History Collections made in Alaska, 1877-1881," reports S. carolinus from Sitka, which is, I think, the southernmost record heretofore. * Dr. J. G. Cooper informs me that a sknll of a tropic bird was fonud by Mr. Gruberon the coast of Mariu County about twenty years ago. W. E. 13. GENERAL ORNITHOLOGICAL NOTES. 87 Puffinus griseus (Gmel.), Putfinus gavia (Forst.) and Ster- coiririus pomarinns (Temm.) ON the Coast of California. By W. E. Bryant. A specimen of Piitjinas griseus, now in the collection of the California Academy of Sciences (No. 340) was washed ashore near San Francisco in 1887. This species has not been previously known from Pacific Ocean. Dr. Cooper mentions- a blackish species, found by him on the coast of California, and supposed to be the young of P. cveatopus, with which it was associated. The bird in question has been identified by Mr. Ridgway. The Black-vented Shearwater (Puffinus gavia) has been known from the Pacific Coast only from two specimens taken at Cape St. Lucus by Mr. John Xantus, and a single bird found by myself on Guadalupe Island, Lower Cali- fornia. Mr. E. C. McGregor found one dead upon the beach at Santa Cruz, Cal., Oct. 17, 1888, (No. 319, ? , coll. E. C McG.) It will probably be taken on the coast of Califor- nia much farther north. In the collection of the California A^cademy of Sciences is a specimen of the Pomarine Jaeger (Stercorarius poma- riiius), No. 341, which was found on the ocean beach, San Francisco, after a heavy storm in 1887. The only no- tice I find of its occurrence on the Pacific Coast is of a single bird taken by Mr. Elliott on the Pribylof Group, Alaska. Notes on the Occurrence of Fregata aquila, Clangula hyemalis and Oceanodroma furcata ON the coast of Northern California. By T. S. Palmer. During a short stay in Eureka, this spring, I had the pleasure of examining the collection of mounted birds be- longing to Mr. Chas. Fiebig of that city. Mr. Fiebig has kindly furnished me with the data concerning the following- species : * Ank, VoL III., p. 125. 88 CALIFORNIA ACADEMY OF SCIENCES. Fregata aquila. Man-o'-War Bird. A female of this species was siiot by a market hunter on Humboldt Bay, Oct. 5, 1888, and presented to Mr. Fiebig, who now has it in his collection. This is believed to be the first well authenticated record of this bird on the coast of California. Its claim to a place in the avifauna of this State having heretofore rested on a skull, supposed to be of this species, found on the Farallon Islands a number of years ago.^ Clangula hyemalis. Old-squaw. A rare species on this coast, especially in California. A male was taken on Humboldt Bay, Oct. (15 ?), 1888. Oceanodro7na furcata. Fork-tailed Petrel. A specimen was picked up on the beach of Humboldt Bay, by Mr. J. B. Brown, on February 16 or 17, 1887. It was one of a number which had been killed by a recent storm and washed up on the beach. The fork-tailed petrel has been taken within the State on one or two occasions before, but the instance cited above seems to show that it is common, if not abundant, off our coast in winter, and like the Pacific fulmar, is sometimes destroyed in considerable numbers by severe storms. The Identification of Californian Nests and Eggs of THE Genus Empidonax. By H. K. Taylor. It is, I think, a fact of interest and one not before re- marked, that of the four species of Empidonax found breeding in California, the eggs of two of them, E. difficilis -And E.pusil- liis, which are spotted and indistinguishable, may be identi- fied by the great difference in construction and especially position of nests. Three nests of E. pusillus, found by me this year near Pleasanton, are much deeper and more compact than any of *Proc'. Cal. Acad. Sci., Ser. 2, Vol. I, p. 41. GENERAL ORNITHOLOGICAL NOTES. 89 the many nests I have seen of E. dlfficilis. Tliey were built in the forked branches of small trees, which is the invariable rule, while the nests of E. difjicilis are never found in such situations. Occasionally a nest of E. dlfficilis is seen in the top of a tree trunk, where large branches diverge, but it is noticed that in such cases they occupy a depression in the bark, never being supported by twigs at the sides like the nests of E. pusillus. Mr. L. Zellner, of Los Angeles, writes to me : "I have collected seven or eight nests of this species \_E. pusillus] this season, in the early part of June. They contained from three to four eggs each, and were all placed in the forks of willows from four to eight feet from the ground." The nests of E. hammondi and E. ohscii7nis are said to be sometimes built in forks, but as their eggs are unmarked there is no danger of confounding them with the eggs of either E. difficilis or E. pusillus. Just how far it is possible to identify the eggs of E. hammondi and E. obscurus from the situation and construction of the nests and the size of the eggs, must be learned from a large number of instances obtained from different localities. An Omission fkom the A. 0. U. Kevised List. By W. W. Price. In the "Auk" (Vol. V., p. 425) appeared a record of the capture of Xantus's becard (Platypsaris albiventris) in the Huachuca Mountains, Southern Arizona, seven miles north of the Mexican boundary, which has been overlooked in the revision of the check list of North American birds. A day or two after it was taken the bird was sent to Mr. Robert Eidgway for identification, and remained in the Smithsonian Institution several months. The record seems to be of some importance, as it is not only a species new to [7J 90 CALIFORNIA ACADEMY OF SCIENCES. the United States avifauna, but also a new genus and fam- ily within the United States. A Specimen of Passerella iliaca taken in Califoenia. By W. E. Bryant. Mr. A. M. Ingersoll, of San Diego, has sent to me for examination a male fox sparrow (P. iliaca), which he col- lected at Poway, San Diego County, January 3, 1888. The bird is in good plumage and not different from Eastern ex- amples. In the appendix to Hist, of N. A. Birds, Vol. Ill, p. 516, mention is made of "The capture of a specimen ex- actly intermediate between P. iliaca and P. toionsendii, at Saticoy, California, December 14, 1872, by Dr. Cooper." ENTOMOLOGiaAL CONTRIBUTIONS. 91 ENTOMOLOGICAL CONTRIBUTIONS. BY H. H. BEHR. I. The Genus Neophasia Belir. The late Baron Terloot de PopeJaire, many years ago, while on a journey through the pine forest region of the Sierra Madre, from Dnrango to the Pacific Coast, collected a peculiar butterfly, and, having no better means of pre- serving it on a hurried trip through a region infested by Indians, pressed it in his pocket-book. This specimen, considerably shattered, but showing all its essential characteristics, came into my hands. I saw it to be a near relation of Pieris Blenapia Felder, and a close inspection of the nervation of its wings revealed the fact that the insect could not be comprised in the genus Pieris. A careful study of Menapia, which it so much resembled, made it evident that both species were congeneric, belong- ing to a new genus having characteristics of Leptalis and Euterpe, and even of the Asiatic genus Pontia, and the European Leucophasia. On this species, Menapia, and the new one which I called after its discoverer Terlootii, by misprint Terlooil, was founded the genus Neophasia. Since that time various webs of very peculiar structure have reached me from different parts of Northern Mexico, with the statement that they were the work of caterpillars living in them through the rainy season, and producing a butterfly, not a moth, early in spring. These nests were only found at an elevation beyond permanent human habi- 2d Ser., Vol. II. October 15, 1889. 92 CALIFORNIA ACADEMY OF SCIENCES. tation, but there in great profusion on the Madrono, an Ar- butus, probably identical with our A. menziesii. As these webs can be made very useful for certain pur- poses, several members of the Academy tried to obtain living insects, which could be easily acclimatized in our madrono forests, or into plantations where it could be more easily protected. One result of these efforts was to prove that it was not quite as common in the fastnesses of the Mexican Sierras as it had appeared. The evergreen foliage seemed to preserve the webs for an indetinite time, and all our correspondents agreed that they were obliged to exam- ine many of them before they found one inhabited. The few which were sent always arrived with all their in- habitants dead, and so badly shattered that they could not be used as specimens for the entomological cabinet, but not so completel}^ that it was impossible to classify them generic- ally, and their nervation showed that they belonged to a third species of the genus NeopJiasia. An invoice which I received from Cozihuiriachic, which probably came from some mountain ridge of that neighbor- hood, contained webs full of Terlootii developed in transit, and smothered by the close packing, proving that species had the same larval habit and food plant as the inhabitants of the former webs. There were now, including llenapia, three species of the same type, two of them connected besides by their pecidiar method of life in the larval state. In Kirby's Catalogue of Diurnal Lepidoptera iS found a genus Euclieira with a single species, E. socialis, described by -Westwood in Trans. Entom. Soc. i, 44 (1836), and cred- ited to Mexico. The volume of the Transactions is inac- cessible to me, but the specific name socialis caused a vague suspicion that the genus was identical with NeopJiasia, a supposition which has been confirmed by an article from ENTOMOLOGICAL CONTRIBUTIONS. 93 Dr. Jesus Aleman in La Naturaleza, Vol. vii, where he de- scribes E. socialis and disc asses its uses, and adds a plate showing the butterfly in the act of laying eggs on an arbutus leaf, the caterj)illar on a branch, and a colony of chrysa- lides in the v^eculiarly shaped web so characteristic of the species. As there is not the slightest doubt that Terhotii and Menapia belong to the same genus as socialis, it naturally follows that the name Neopliasia Behr, must be retired in favor of ^wc/ieiVa"^ Westw., which is the older and a most appropriate name, referring as it does to the workmanship of the larva, most unusual in the series of Pier ides, and of the Diurnal s in general. The genus Eucheira, comprising now three species, their diagnoses for greater distinctness may be formulated as follows: 1. E. SOCIALIS Westw. Al?e anticae, macula alba discoi- dali signatce, cunctse fascia alba per mediam alam trans- versa, nee non punctis albis marginalibus instructae. 2. F. Terlootii Behr.

The larval state of socialis and Terlootii is entirely the same, but as to that of Menapia my information is very im- perfect. It is always found in regions abounding in conif- erous trees, and has been supposed to feed on them, but as Madrono is usually found in the same districts, it is pos- sible that its food plant is the same as that of the other spe- cies, although Arbutus is as exceptional a food for Fierids as a conifer would be. The peculiar silky web made by the other species has never been observed in the range of Menapia, and as such a conspicuous object could hardly have escaped observation, the larvse (still unknown) proba- bly do not form them. It may be that it is a social weaver only in its earliest stages, as is the case' with Aporia crategi, the food plant of which is also an anomaly in the series of the Pierides. II. A NEW Cerocampide. By the kindness of Professor J. J. Rivers, of our State University, I received a caterpillar preserved in alcohol, and two living chrysalides, which in process of time furnished a pair of moths belonging to the series of the Cerocampides. A very similar insect was described and figured in Smith Abbott's Insects of Georgia, under the name Notodonta concinna. A close examination of Professor Rivers' specimens has convinced me that they canuot belong to the genus Nofo- donta, but that they are most related to Bryocan^ja. It may be that the species deserves generic rank, but I leave this question to other Entomologists, who have in a full series of this and related types better means for comparison.

The caterpillar rests with its anal joints lifted after the manner of Notodonta Ziczac or rather N. concinna, so that the anal feet do not touch the leaf on which it rests, but it uses them, though they are less developed than the other prolegs and rather imperfect for locomotion, according to the ob- servation of Professor Kivers. The skin is naked and fur- nished with horny but hairless tubercles, which increase in length towards the head and anal extremity, forming blunt spinose appendages; dorsal surface longitudinally striped with alternate black and white lines, the sides olive green with a few dispersed white spots, bordered by black lines; head and girdle of fleshy tubercles encircling the first pair of footless joints between the legs and prolegs, bright red. It is of course possible that the colors have been modified by the preservative alcohol. TJiis moth appears to form a transition from the Cero- campides to the Notodontides. It may possibly be considered a new genus in which N. concinna Smith, would be a second species. The slightly dentate outline of the external mar- gin of the forewings distinguishes the insect from other species of Dryoccimjoa and approaches it somewhat to the Notodonta group, but the nervation of the wings, and its larval characteristics, bring it without doubt into the former. In markings it bears some resemblance to the European Hyhocampa Milhauscri. It also shows a certain likeness in nervation and outline of wings, as well as in texture of 96 CALIFORNIA ACADEMY OF SCIENCES. thorax and patagia, to the Australian Danima Banksice, but the entirely different sphingiform larva of the latter prove that this superficial similarity is rather of analogy than of affinity. As well as we are able to judge from the material and literature at our command this is the only species thus far found in California, of the series of the Cerocampides, so well represented in the Atlantic States and in tropical America. CYCLONIC WINDS. BY P. S. BUCKMINSTER. During the summer of 1878, at Belleville, Esmeralda Co., Nevada, I observed a movement in cyclonic winds, which I believe has not heretofore been recorded, and which is shown in the diagram. A. General Movement. B. Large Circular Movement. C. Small Circular Movement. Heretofore circular winds have been represented as hav- ing three movements, viz:^of direct projection, of revolu- tion, and a vertical movement. My observation was of a well-defined and strongly marked smaller circular move- ment, in and upon the line of the general circular move- ment, which was continuous and sustained during the whole time of observation. This movement was manifested by a 2d Ser.. Vol. II. (8) October 18, 1889. 98 CALIFORNIA ACADEMY OF SCIENCES. cylindrical film of sand having a diameter of approximately twenty feet, moving slowly upon its direct coarse and with a velocity of about ten feet per second around its central axis. In and upon this moving circle were six small revolv- ing circles not exceeding one foot in diameter and having a greater velocity, probably inversely proportionate to their diameters. Their greater velocity enabled them to take up from the surface of the ground more sand and debris than the larger circle, and as a consequence, they maintained strong and independent columns upon the larger but weaker one. The movement, which was from right to left in its circu- lar projection, passed within a few rods of me. Approach- ing, it was upon ground having a loose sandy surface and free from obstructions. Near me the ground presented a few scattered shrubs with sand intervening; beyond, there was open sand again, then a street with a line of buildings upon one side; beyond the buildings were: first, sand, then sand and shrubs. The fourth movement was strongly de- fined when I first noticed the general movement, and so continued during the time I was able to observe it. When the movement reached the ground covered with shrubs and one of the smaller movements encountered them, it would apparently become obliterated, but directly it would appear in its place again, simply having been broken at its earth contact. The movement passed directly over the buildings noted and again made ground contact, maintaining its sev- eral movements, which were sustained while it was within my observation. In the recorded observations of devastation effected by tornadoes, we find instanced the twisting of branches of trees about their trunks, the turning of chimneys upon their bases without being thrown dow^n, the whirling of objects in the air, the erratic movement of bodies, etc., none of which are explainable by either or all of the movements heretofore recognized, but which are readily accounted for by this fourth movement. CYCLONIC WINDS. 99 This fourth movement existing in a tornado might not constantly manifest itself, for when obstructions are en- countered, the general movements are disturbed, and the circular ones raised from earth contact. But when there are no serious obstructions the surface air is enabled to flow in freelj^ and fully and produce a complete C3'lindrical move- ment, then, and following such an attained condition, should occur manifestations of this fourth movement. A REVIEW OF THE ERYTHRININiE. BY CARL H. EIGENMANN AND ROSA S. EIGENMANN. (With Plate I.) The Erythriniii8e is a sub-family of the Characinidse. It has usually been separated from the remaining sub-families on account of the absence of an adipose fin. This absence of the adipose fin, when isolated from other characters, seems to us to be of little value in classification. The gen- era of this sub-family are more closely related to the Anos- tomatinas than they are to the Curimatinae, with which they have usually been associated. The species of this sub-family are, with two exceptions, confined to the eastern slopes of South America and the ad- jacent islands. The specimens examined belong to the Museum of Com- parative Zoology at Cambridge, Mass. ERYTHRININ.E. Adipose fin none. Gill opening wide, the membranes slightly united, free from the isthmus.

This seems to be one of the commonest food fishes of all the rivers east of the Andes. It is found in the whole course of these streams, occurring in the Amazons between Para and the Rio Huallaga. The coloration varies considerably with the localities and with age, the different localities regulating the degree of light or darkness. In specimens .06 m. long there is a con- spicuous dark lateral band from the tip of the snout to the base of the caudal; in larger specimens portions of the band become broadened to form blotches while the remaining portions are margined by a dark line and bordered by a light or silvery area; with age the band, and afterwards the blotches disappear; in the largest specimens the dorsal surface is thickly covered with small spots. The fin rays of the vertical fins are spotted and the spots frequently extend on the membrane to form bands. The pectoral and ventral fins are occasionally dusky without distinct spots. The belly is white, occasionally spotted; the chin frequently crossed by purplish bars; there is usually a round dark spot at the upper posterior angle of the caudal peduncle. The scales are uniformly larger in this species than in microlepis. In a specimen .39 m. collected by Mr. Wheat- land at Buenos Ayres there are 12, 11, 11, 9 series of scales from one lateral line to the other in respectively the first, second, third and fourth series behind the dorsal; this is due however to the splitting of the median scales of the back. Several other specimens present similar conditions. The scales of the lateral line vary from 39-43. The size of the canine teeth and the lingual patches of teeth vary considerably. We have been unable to detect REVIEW OF THE ERYTHRININ^. 105 any uniformity of variation, one organ varying indiscrimi- nately of another. The food of this species consists at least partly of other fishes. II. Erythrinus.

Habitat: Eio Parabyba to Guiana and Peru; Trinidad, The young of this species is sometimes uniform dusky, without spots on the fins. This is doubtless the condition figured by Marcgrave. Dr. Gunther identified ('64, 283) Erythrinus vittatus C. & v., with E. anitceniatus. He also ('68a, 239) pronounces specimens from Trinidad, presumably the cinereus of Gill, identical with unitceniaius . Dr. Stein dachner ('76b, 38) described his lessleri from three specimens 2'' 8'''- 4'' 6"' long, collected at Bahia. We have examined two of these specimens and also a num- ber of others from the same locality, and have found teeth on the pterygoids in very narrow patches. On comparison with the smallest specimens from other localities, which were larger however, the pterygoid patches of teeth were a little wider. There cannot be the least doubt that the Jcessleri of Steind. is the young of unitceniatus. We have examined 90 specimens .07-. 31 m. from Sao Matheos; Kio Doce; Bahia; Para; Cudajas; Obidos; Villa Bella; Serpa; Santarem; Silva, Lake Saraca; Hj^anuary; Maues; Porto do Moz; Curapera; Tabatinga; Lake Jose Assu; Goyaz. The typical specimens have a dark lateral band, which when present is most marked in specimens .20 m. long. This band is sometimes absent in specimens otherwise like those with the band. There are three dark bands extend- ing from the eye to the edge of the opercle; these are also sometimes wanting. The dark opercular blotch can be seen in all specimens. Specimens .20 m. long from Sao Matheos are uniform dark-brown, the fins of a similar color, without any spots. Other specimens from the same REVIEW OF THE ERYTIIRININ.E. 107 locality have the dorsal aud anal spotted, and a dark spot at the base of each scale, and another has the dark lateral band. Two specimens, .09 m., from Goyaz, have the bands of the head and opercular spot quite marked, and the sides with more or less interrupted vertical streaks. In tliese specimens no pterygoid teeth could be detected — a condition which may be explained by their age. In the young the pterygoid teeth are minute and in seem- ingly but a single series, or entirely wanting: in the old the patches are almost as wide as the palatine patches, and contiguous. The young of this species can be readily dis- tinguished from that ot salmoneus by the color. 2. Erythrinus salvus. Erythrinus salvus Agassiz '29, 41 (Sau Fraucisco); M. & T.

The species salvus and gronovii both differ from unitceni- atus in the color of the caudal. The first was based on a specimen taken from the stomach of Macrodon. The differ- ence in the localities seems to be the chief reason for separ- ating the species. 3. Erythrinus erythrinus. Cyj)rinus cylhidricus L. Mas. Ad. Fred. 77, pi. 30, 1754.

Dr. Steindachner gives a good description of this species and identifies both the longipinnis and brevicauda with it. 108 CALIFORNIA ACADEMY OF SCIENCES. As we have not been able to find any specimens with fins approaching the length described for longipinnis we have kept that species distinct. Sixty-six specimens, .055-. 175 m. Surinam; British Gui- ana; Gurupa; Taj apuru; Porto do Moz; Santarem; Cudajas; Lago Alexo; Manacapuru; Teffe; Tabatinga; Rio Janeiro; Ueranduba. In the specimens examined the ventrals were never found to extend beyond the origin of the anal, and the longest dorsal ray is always shorter than the head. The young of this species can readily be distinguished by the large caudal and humeral spots; the sides of the young are usu- ally marked with dark cross shades. 4. Erythrinus longipinnis.

'75a, 2. pi. 1, fig. l-2a (Stagnant water near Barra do Rio Negro; Cudajiis; Gurupa; Tabatiuga). Habitat: Amazons from Gurnpa to Tabatinga. About two hundred specimens, the largest 09 m. Tabatiuga; Cudaja«; Obidos; Hyanuary; Jose Fernandez; Manacapu- ru; Jutahy; Curupira; Santarem; Silva, Lake Saraca; Villa Bella; Gurupa. Teeth of the outer dentary series decidedly longer and stronger at the side of the jaw; teeth of the outer interjnax- illary band strongest at the middle of the mouth. Usually very light brown. Adult with a band extending from the symphysis about half way to the caudal. In the male a dusky area below this band. Sometimes one or two access- ory bands similar to the median band. In the young this band extends little beyond the first scale behind the head. A dusky area at the occiput, another some distance in front of the dorsal, an orange streak between them. The dorsal spot is margined below by a slightly lighter area; the caudal is frequently indistinctly barred; the outer or an- terior rays of the fins frequently white. REVIEW OF THE ERYTHRININ^. Ill Ventrals sometimes reachiog anal, usually falling far short of the anal. 5. Pyrrhulina brevis. Pyrrhidlna brevis Steiud., '75a, 6, pi. 1, fig. 3-4 (Mouth of Rio Negro; Cudaja^; Tabutinga; Rio Negro, near Mauaos). Over twenty specimens, the largest .065 m. Tabatinga; Lago Alexo; Cudajas; Manaos; Montalegre; Obidos; Villa Bella. This species is closely related to semifasciata and guttata. In the female the sides are plain with sometimes lighter spots at the base of the scales, as in guttata. There is usu- ally a dark band on the side of the head. In the males there is a dusky line along the head and the sides, regions below the level of this line in the adult are also dusky. The fins in the male are also slightly margined with dark. The dorsal spot is indistinct. In three specimens .028 m. long, from Tabatinga, there is a conspicuous dark serrate- margined band from the caudal to the head, and a narrower smooth-margined one on the head. The dorsal spots in these specimens are much more marked than in the larger. Four specimens from Montalegre, the smallest .03 m., have the sides plain, and two male specimens from Cudajas, .055 m. , have a dark blotch behind the head. The fins are much better developed in the male than in the female. The ven- trals in the male reach to the anal, and the anal to the caudal. The longest ray of the dorsal is little longer than the head. Our specimens do not agree with Dr. Steinclachner's figures in the position of the dorsal and anal. 6. Pyrrhulina maxima sp. n. Type No. G343; one specimen. .08 m. to base of caudal. Tabatinga. Boiirget. This species is closely related to P. brevis and P. nattereri.

The scales are 112 CALIFORNIA ACADEMY OF SCIENCES. partly lost, so an exact count is impossible. As already stated, Dr. Steindachner's figures of P. brevis do not agree with the specimens examined by us. The comparisons made in the key are based on the specimens examined, 7. Pyrrhulina nattereri. FijrrhuHaa natlererl Steiud '75a, 8, pi. ii, fig. 5-5a (mouth of Rio Ne- gro; Obidos). Habitat: Amazous from Obidos to Cudajas. One hundred and sixty specimens, the largest .055 m. Rio Trom- betas; Villa Bella; Manaos; Silva, Lake Sarac.i; Hyanuary; Cud- ajas; Jatuaraua; Obidos. This is the most slender species of Pyrrhulina. It can easily be recognized by the color. Each scale has a silvery center and dusky margin. In some specimens the color markings of the lower half of the sides are obliterated by a dusky lateral band, the region above it being lighter than usual. The fins vary greatly in height. In the largest specimen the height of the dorsal is little less than half the length, and the ventrals reach beyond the base of the anal. Usually the dorsal does not reach to the caudal, and the ventrals not to the anal. 8. Pyrrhulina guttata. Pyrrhulina guttata Steind. 75a, 10, pi. ii, tig. 6-6a (Obidos; Cudajas; Tabatinga; Rio Negro). Habitat: Amazous from CJurupa to Tabatinga, Kio Negro. The relative abundance of this species may be seen from the number of specimens from each locality. Gurupa, 3 specimens; Tajapuru, 11; Villa Bella, 6; Obi- dos, 399; Santarem, 1; Manacapuru, 24; Cudajas, 8; Tab- atinga, 31; Curupira, 2. The largest specimen is from Cudajas, and measures .098 m. The color varies greatly, the markings are more constant. The specimens from Cudajas are light straw colored; those from Obidos dark brown, lighter below. There is usually a silvery white spot at the base of each scale of the sides; they are sometimes found on the median scales of the tail REVIEW OF THE ERYTHRININ^. 113 only, and sometimes entirely wanting. The sides of the head and snout are always plain. The dorsal spot varies in size and intensity of color; the middle caudal rays have three faint dusky cross-bars; the middle of the last anal ray is usually milky white, the white being bordered above and below by dusky areas; tips of the outer ventral rays usually milky white. Fins always low, the ventrals not nearly reaching the vent. 9. Pyrrhulina argyrops. Pi/rrhulina argyrops Cope '78a, 694 (Peruvian Amazon). Habitat: Marailou.
